Long-Term Risks of Benign and Malign Complications after Endoscopic Sphincterotomy in the Management of Benign Biliopancreatic Pathology: A Cohort Study.

Background:  Endoscopic retrograde cholangiopancreatography (ERCP) is the preferred technique for treating pathologies of the bile duct. It has been suggested that this procedure, combined with sphincterotomy, may influence the subsequent development of long-term complications. The main objective of this study was to determine the long-term complications of biliopancreatic disease after ERCP and their potential association with the development of biliopancreatic neoplasms.

Cost-effectiveness analysis of the diagnosis of temporal arteritis.

Unlabelled: Temporal arteritis (TA) is the most common form of systemic vasculitis. Its diagnosis is based on criteria proposed by the American College of Rheumatology (1990), and its treatment is high-dose corticosteroids. Our objective is to assess the cost of diagnosing TA, and secondarily, cost-effective analysis of different diagnostic strategies (clinical, biopsy, doppler ultrasound) and therapeutic strategies (corticosteroid suspension).

Effect of Remote Ischemic Preconditioning on the Incidence of Contrast-Induced Nephropathy in Patients Undergoing Endovascular Aneurysm Repair (Remote Ischemic Preconditioning-Endovascular Aneurysm Repair Study).

Background: Contrast-induced nephropathy (CIN) is a major inconvenience in the use of iodinated contrast media (ICM) and it is associated with a significant increase in morbidity and mortality and cost of hospitalization. Remote ischemic preconditioning (RIPC) is a noninvasive and cost-effective tissue protection technique that has showed to be beneficial in decreasing renal insult in patients receiving intravascular contrast.

Aim: The primary outcome of this study is to evaluate the impact of RIPC on the incidence of CIN in patients undergoing endovascular aneurysm repair.

Impact of nutritional and inflammatory status in patients with critical limb-threatening ischemia.

Background: A pro-inflammatory state and a poor nutritional status have been associated with severity and prognosis of patients with peripheral arterial disease (PAD). The clinical applicability of the different pre-operative nutritional and inflammatory biomarkers in patients with critical limb-threatening ischemia (CLTI) was analyzed.

Methods: A retrospective observational study was performed, that included all patients with CLTI revascularized from January 2016 to July 2019.

Off-Label Use of a Flared Endograft Limb for Treatment of a Complicated Anastomotic Abdominal Aortic Pseudoaneurysm: Reverse Deployment Throught Axillary Artery.

A case of complicated abdominal aortic pseudoaneurysm not suitable for open repair is described. It was treated by means of endovascular methods with a flared endograft limb. The uniqueness of this case is the absence of a suitable femoral access, requiring the deployment of the graft in a reversed configuration through axillary artery.

Statistical techniques for predicting rupture risk in abdominal aortic aneurysms: A contribution based on bootstrap.

The morphometry of abdominal aortic aneurysms (AAA) has been recognized as one of the main factors that may predispose them to rupture. The need to quantify the morphometry of AAA on a patient-specific basis constitutes a valuable tool for assisting in rupture risk prediction. Previous results of this research group have determined the correlations between hemodynamic stresses and aneurysm morphometry by means of the Pearson coefficient.

Thirty-three vascular residency programs among 13 countries joining forces to improve surgical education in times of COVID-19: A survey-based assessment.

Background: Academic interaction with mentors has almost become minimal due to the current pandemic of COVID-19. The objective of this study is to introduce how a group of vascular surgery residencies joined forces to improve surgical education in times of COVID-19.

Methods: On May 2020, a group of Hispanic American vascular residency programs created webinar sessions of arterial and venous clinical cases among vascular residents across Latin America and Europe.

Doppler Ultrasound as a Unique Diagnosis Test in Peripheral Arterial Disease.

Background: The aim of this study was to analyze duplex ultrasound (DUS) and intraoperative angiography concordance for diagnosis of lower limb peripheral artery disease and its value for surgical planning.

Materials And Methods: This was a prospective, observational study, including patients who underwent revascularization of the lower limbs during 2018, diagnosed by DUS only or combined with preoperative computed tomography (CT) angiography. The concordance between preoperative DUS or CT angiography and the intraoperative angiography was studied using the Cohen kappa coefficient (k).

Celiac trunk segmental arterial mediolysis: a rare cause of arteriopathy.

A 50-year-old male patient, without a previous medical history, presented sudden severe abdominal pain with no alterations in the blood analysis. A CT-Angiography (CTA) was performed that showed a wall thickening of the celiac trunk extended to the hepatic artery with a filiform lumen and no involvement of the splenic artery. There were no signs of intestinal or liver ischemia, therefore no further radiological tests were performed.

Effectiveness of the Combined Treatment of Functional Electrical Stimulation and Deambulation in Diabetic Arteriopathy.

Objective: To determine whether functional electrical stimulation (FES) is able to improve ischemic pain and quality of life of patients with diabetic arteriopathy (DA) in grade-IIa Leriche-Le Fontaine.

Material And Methods: This is a single-blinded, randomized, prospective cohort study. We included patients diagnosed with grade-IIa Leriche-Le Fontaine peripheral arterial disease in both lower extremities with and without diabetes mellitus (DM).

EVAR Approach for Abdominal Aortic Aneurysm with Horseshoe Kidney: A Multicenter Experience.

Background: Horseshoe kidney is a congenital abnormality, with an incidence of 0.25% of the total population. Only 0.

Laparoscopic Appendectomy in the Setting of Clinical Prediction Rules.

Purpose: Acute appendicitis (AA) is the most frequent surgical entity in the emergency department, but its correct diagnosis remains challenging. To improve diagnosis, clinical prediction rules (CPRs) have been created to establish objective scores for the probability of suffering AA. In this study, we establish scores indicating whether laparoscopy would be superior to clinical observation or repeat diagnostic test.

A Unique Case of Horner's Syndrome Following Subintimal Haematoma Within an Atherosclerotic Plaque.

We describe a patient with Horner's syndrome caused by an extensive intraparietal hematoma in the wall of the internal carotid artery confused with an arterial dissection. Detection of such pathology instead of dissection or arteritis is important as the management is different. As far as the authors know, it is the first case in which a haematoma within an atherosclerotic plaque is clinically related Horner's syndrome.

Methods: A prospective multicentric European registry of patients receiving the E-liac Stent Graft System® was conducted. Endpoints of the study included the technical success as well as periprocedural events and 30-day endoleaks, reinterventions, internal and external iliac artery patency and mortality.

Radioprotection Measures during the Learning Curve with Hybrid Operating Rooms.

Background: Endovascular procedures come with a potential risk of radiation hazards both to patients and to the vascular staff. Classically, most endovascular interventions took place in regular operating rooms (ORs) using a fluoroscopy C-arm unit controlled by a third party. Hybrid operating rooms (HORs) provide an optimal surgical suit with all the qualities of a fixed C-arm device, while allowing the device to be controlled by the surgical team.

Endovascular Repair of a Descending Thoracic Aortic Aneurysm With an Aberrant Left Subclavian Artery Associated With an Infrarenal Aortic Aneurysm.

Aneurysms involving a right-sided descending thoracic aorta with an aberrant origin of the left subclavian artery are rare. We describe the successful surgical repair of this vascular anomaly by the combined use of a left carotid to subclavian artery bypass followed by endovascular stent graft placement to exclude the aortic aneurysm. We also review the literature associated with this particular anatomic presentation.
